Formerly Utilized Sites Remedial Action Program

Published Jan. 18, 2024
Under the Formerly Utilized Sites Remedial Action Program (FUSRAP), the U.S. Army Corps of Engineers (USACE) is cleaning up sites with contamination resulting from the Nation’s early atomic energy program. FUSRAP was initiated in 1974 to identify, investigate and, if necessary, clean up or control sites throughout the United States contaminated as a result of Manhattan Engineer District (MED) or early Atomic Energy Commission (AEC) activities. Both the MED and the AEC were predecessors of the U.S. Department of Energy (DOE).

Congress transferred administration and execution of FUSRAP cleanups from the DOE to USACE in October 1997. USACE continues to address sites the DOE began, sites that were referred to USACE by the DOE Office of Legacy Management under a USACE/DOE Memorandum of Understanding, and one site added to the program by Congress.

Learn more about the USACE completed FUSRAP sites that have been transferred back to DOE-LM for long-term stewardship.

The Buffalo District is charged with managing the FUSRAP sites within the Great Lakes and Ohio River Division. Read more about the story of the Buffalo District’s FUSRAP sites.


USACE FUSRAP objectives are to safely, effectively and efficiently:

  • Identify and evaluate sites where authority and the need for a response action exist.
  • Clean up or control FUSRAP sites to ensure protection of human health and the environment.
  • Dispose of or stabilize radioactive material in a way that is safe for the public and the environment.
  • Perform work in compliance with applicable federal, state and local environmental laws and regulations.
  • Return sites for appropriate future use.
